用埋设试件的方法，研究了１Ｃｒ１３、１Ｃｒ１８Ｎｉ９Ｔｉ两种不锈钢在酸性，中性及 碱性土壤中经过１、３、５年三个试验周期后的腐蚀特征。结果表明，两种不锈钢在酸性及中性土壤中腐 蚀轻微，在高盐碱性土壤中腐蚀严重，以点蚀为主。
Corrosion behavior of 1Cr13 and lCrl8NiSTi in soils were studied. The results showed that corrosion of stainless steels was mainly due to the contents of C1- and SO:- in soils, and there was a good correlation between the weight loss of corrosion and the contents of C1- and SO:- in soils. The pH of soils and corrosion potential were other important factors determining the corrosion rate of the stainless steels in soils. Some severe pitings of 1Cr13 were observed in alkaline soils.
